Abstract.The notion of essentially slant Hankel operators is generalized to $k$-th order $(k\ge 2)$ essentially slant Hankel operators on the space $L^2(\TT)$, $\TT$ denoting the unit circle in the complex plane. The study is further carried to compressions of such operators. It is shown that for a fixed integer $k\ge 2$, a Rhaly operator is the compression of a $k$-th order essentially slant Hankel operator iff it is the compression of a $k$-th order essentially slant Toeplitz operator.
